Red X on tv screen after power outage

I'd call AT&T and ask for a replacement to be sent. It sounds like it's fried, but I'm just a customer.

You can try the "hard reset" which I think is achieved by pressing the power, OK and down buttons all on the receiver, but that probably won't do anything.

They'll send a new box via UPS or FedEx. As soon as you get the new one, take the old one and your billing number to any UPS or FedEx store and they'll do the rest.

...unless @skeeterintexas has any ideas.

Assuming they also have Internet, is that working?

Is the Gateway powered on and lit up appropriately?

What sort of lights are on the front of the TV Receiver?

Thank you so much for the suggestion -- have tried the hard reset, and as suspected, did nothing. Suspect problem is box itself; am calling AT&T today. (Yes, they do have internet, gateway powered and all correct lights on, everything on TV receiver looks normal. Sigh).

One last thing to try, but I doubt it'll work.

Do you have another receiver? Put that one at the "bad" TV. Put the "bad" box in the other location.

But it 99.9% smells like you need replacement equipment.

Thanks all -- got AT&T out there yesterday, and they determined that it was indeed a bad box, only option was to switch it out. Now waiting to see if they bill us for the visit -- despite the $250/month my parents pay for all the stuff -- as potential "user error" that led to the bad box vs. an actual bad box that died immediately following the power outage. I can see why cable companies have such poor reputations. Appreciate you all.

The good news is that they shouldn't charge because the tech came out and, I assume, tested stuff with his equipment. They typically only charge if it's something like a loose connection or bad batteries in the remote...things any customer should know to check on their own.

You should have your parents call for a discount. It probably won't be much, but $30-50 for 12 months definitely adds up. If they *do* get charged, I'd absolutely call. If they can't waive the repair fee, they should be able to give you enough of a discount to reduce the repair fee.

Sidenote: Because U-Verse doesn't require coaxial (black and round) cable wire, it's not cable TV, even though it has equipment which functions like cable TV. I believe the technical term is IPTV or "Internet Protocol TV" although I could be wrong.

Cable TV is generally services like Xfinity or Spectrum which do require that black coaxial cable.

This is why you'll see the articles "How to stream the Super Bowl without cable" and it's all articles advertising Hulu or YouTube TV.

And yeah, it does frustrate me when people say "I have cable via YouTube TV" even though they know they cut their cable.
